        The name <code class="computeroutput"><span class="identifier">execution</span><span class="special">::</span><span class="identifier">set_value</span></code> denotes a customisation point
        object. The expression <code class="computeroutput"><span class="identifier">execution</span><span class="special">::</span><span class="identifier">set_value</span><span class="special">(</span><span class="identifier">R</span><span class="special">,</span>
        <span class="identifier">Vs</span><span class="special">...)</span></code>
        for some subexpressions <code class="computeroutput"><span class="identifier">R</span></code>
        and <code class="computeroutput"><span class="identifier">Vs</span><span class="special">...</span></code>
        is expression-equivalent to:
